Uses
Primary
- Essential for the production of optical glass
- Essential for some voltaic cells
Secondary
- Key intermediate in the production of lead
- Combined with glycerol produces glass-adherent waterproof cement
- Used in ceramic glazes
- Combined with linseed oil produces a white paint
Natural occurrence
- Lead (II) oxide occurs naturally as the minerals litharge and massicot
Hazards
- Lead (II) oxide is toxic if ingested or inhaled
Production
Extraction
Synthesis
from galena
- Heat galena producing lead sulfate
- 2 PbS + 2 O2 → 2 PbSO4
- Roast lead sulfate producing lead (II) oxide and sulfur trioxide
- PbSO4{PbO + 2 SO3≥1087°C}→
- PbSO4
from lead metal
- Heat molten lead metal in air:
- 2 Pb(l) + O2(g){2 PbO(s)601°C}→
- 2 Pb(l) + O2(g)
